SPEED-REGULATOR FOR HORSE-POWERS.

SPECIFICATION forming part of LettersPatent No. 250,958, dated December 13, 1881.

Application filed September 13, 1881;

T 0 all whom it may concern Be it known that I, BARNARD L. ()Lns, of St. Albans, in the county of Franklin and State of Vermont, have invented a certain new and Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

In the drawings, Figure l is a side elevation of a horse-power fitted with my improved regulator, and Fig. 2 is a section of the iiy-wheel and regulator on line 00 w of Fig. 1.

Ais the fly-wheel, and B the brake-lever, pivoted on the sill of the power for action on the fly-wheel, as usual. The regulator is applied to the fly-wheel as follows:

G is a tripod-plate secured by bolts to to spokes of the wheel.

b is a stud fixed on plate (.r and projecting .in front'of the wheel A at the center.

cis a disk formed with a tubular hub and secured loosely on the stud b.

e is a lever hung by a pin,f, on plate 0; and g g are arms connected with the ends of lever e and extending through loops h k, that are attached near the outer ends of two opposite spokes.

Mare weights fixed on the outer ends of arms g.

(No model.)

p is a rope connected to disk 0 and passing beneath a roller on the outer end of brake-lever B to a fixed connection above on the frame of the'machine.

For operation, the lever e is set with its brake-shoe clear of disk 0 and the break-lever B supported by rope p out of contact with wheel A. The weights on the arms g being near the wheel-rim travel with the mostrapidly moving portion of the wheel and are for that reason most sensitive to centrifugal action. When the weights move out the lever c presses against disk 0. The disk is thus carried around and the rope wound on the disk-hub. The rope acts to raise lever B and draw its brake-shoe into contact with the fly-wheel, thus checking the speed until by such reduction of speed the spring in can draw the arms g inward and release lever 0. By adjustment of springm the speed at which the centrifugal weights act is determined. The lever 0 serves to equalize the centrifugal force of the weights 'upon the disk 0, so that the pressure is uniform.

With this regulator the speed of the fly-wheel can be kept down to a uniform point when light work is being done, while for heavy work the regulator can be set to act only when the work is thrown off by accident or otherwise.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1 In speed-regulators,-the weighted arms g, lever 6, rod 70, spring m, loose disk 0, and rope 10, connected to abrake-lever, combined together and with the fly-wheel A, substantially as shown and described, for operation as set forth.

2. The plate 0, provided with stud b, the loose winding-disk 0, having a tubular hub, spring actuated lever 0, connected with centrifugally-acting weights, and ropep, connected to the winding-disk and brake-lever, substantially as shown and described, combined for operation as set forth.
